I'm not sure about the model number but we installed a new AEG Competence in 2005 and the grill kept switching off and having replaced both the element and the thermostat the fan on the top of the oven became extremely loud. we had a private contractor replace it in exactly the same fashion as the original and in a short time the same thing happened. We got a different private engineer who established that the fan on the top had been installed the wrong way around and instead of circulating the air through the space at the top of the oven it was taking it in the wrong direction entirely. It is our firm belief that this is the manner in which we received the oven as new and was therefore a manufacturing error. It is my intention to take the matter up with AEG but I just haven't got around to it yet,
